This work presents a sinkhole susceptibility and risk assessment mapping in Guidonia-Bagni di Tivoli plain (Italy), travertine sinkhole-prone area where sudden occurrences of sinkholes have happened past recent times. We collected point-like inventory we considered series different sinkhole-controlling precursory factors over the study area, related to its geo-litho-hydrological setting terrain...

In August 2014, a large sinkhole with width of 2.5m, depth 5m, and length 8m was discovered in Seoul followed by an additional 5-8m, 4-5m, 70m the center Seokchon underground driveway

Little is known about large sulfur bacteria (LSB) that inhabit sulfidic groundwater seeps in large lakes. To examine how geochemically relevant microbial metabolisms are partitioned among community members, we conducted metagenomic analysis of a chemosynthetic microbial mat in the Isolated Sinkhole, which is in a deep, aphotic environment of Lake Huron. For comparison, we also analyzed a white ...

The purpose of this study was to investigate the relationships between the plant distribution and the altitude-shape-size characteristics of sinkholes, and the landform characteristics inside sinkholes in the Mediterranean region of Turkey. Block kriging, Factor analysis, Cluster Analysis and Detrended Correspondence Analysis were performed. The sinkhole type and altitudinal zone were found to ...

A multiproxy study of a 7 m long sedimentary sequence from Lake La Parra (39o 50.948’, 1o 52’, 1014 m a.s.l) supported by 11 C AMS and Pb/Cs dates provides a robust, high-resolution hydrological and environmental variability record for the last 1600 years of the Las Torcas sinkhole Complex in the Central Iberian Range. The succession of depositional environments in Lake La Parra sinkhole is con...

13 This contribution illustrates the advantages of integrating conventional 14 geomorphological methods with InSAR, ground penetrating radar and trenching for 15 sinkhole mapping and characterization in a mantled evaporite karst area, where a 16 significant proportion of the karstic depressions have been obliterated by artificial fills. 17 The main practical aim of the investigation was to eluc...
